This book investigates the origins of supernatural and religious beliefs. The author tests associations between various types of beliefs (e.g. witchcraft, monotheism) and various societal characteristics (e.g. mobility, class stratification). Many hypotheses are supported. Theoretical discussion is included, and the author posits that “the belief in a particular kind of spirit springs from experiences with a type of persisting sovereign group whose area of jurisdiction corresponds to that attributed to the spirit” (175).

This chapter examines the variables that are associated with the evil eye belief cross-culturally. Results suggest that the evil eye belief is significantly associated with various socioeconomic and demographic variables. All hypotheses are supported.

This book chapter builds on Horton's 1943 psychoanalytical study of drunkenness. The author tests an overall theory that drunkenness, which facilitates personal and uninhibited interactions, is more acceptable, and therefore prevalent, in societies with loose, rather than rigid, social relationships. Indicators of social rigidity, such as strict socialization or male dominance through patrilocality, are tested for relationships to drunkenness.

This book examines population growth rate and its correlates by testing 274 hypotheses (derived from multiple theories) with an 18-society sample. Forty-one of these hypotheses were significant at the .05 level, leading the author to accept these relationships as reflective of the real world. The 274 hypotheses are grouped into 51 broader hypotheses, and marked by (*) where relationships are significant as designated by the author or by significance p < 0.05.

This article employs a phylogenetic approach to explore traits that might be associated with the cultural transmission of the "witchcraft phenotype" across Bantoid and Bantu ethnolinguistic groups. The authors define the witchcraft phenotype as a set of interlinked traits related to witchcraft beliefs within a society, showing both cross-cultural similarities and regional variations. Despite the widespread historical and geographical presence of witchcraft beliefs, little is known about their evolution and transmission. The article's analysis focuses on the possible ancestral transmission of these traits and their coevolution. The authors suggest that witchcraft phenotypes are often intertwined with beliefs in ancestors, spirits, gods, and other supernatural entities, and like other cultural traits, they can evolve through various mechanisms. Their findings indicate support for phylogenetic transmission of some traits, such as the use of poison to detect witchcraft guilt, but show that other factors such as age and gender do not show evidence of historical transmission.

This study proposes ways in which the environment may affect behavioral and psychocultural processes. Results provide moderate support for a relationship between climate and emotional expressiveness.

This dissertation discusses the divided theoretical approach to how reincarnation, animism, spirits, and general religious beliefs occur within societies cross-culturally. Matlock offers evidence to support Tyler, contradicting the generally accepted Durkheimian approach, arguing that the belief about souls and spirits may originate in dreams and other empirical experiences, in turn informing and shaping social organization. Durkheim argued the opposite, claiming that religious beliefs reflect social organization such as the clan and kinship. The author states 33 quantitative hypotheses to be tested using 30 of the first 60 sample societies available in the HRAF Probability Sample.

Derived from the fear of supernatural punishment hypothesis, this paper explores whether the prosocial attitude of a group or individuals will increase with the threat of punishment from a high god or visible supernatural agent, such as sorcerers and witches. The author found that fear of supernatural punishment did not affect prosocial behavior and suggested that religious beliefs may give rise to institutions with the task of enforcing social compliance rather than direct control.

This book examines naming practices cross-culturally. The author posits that naming practices help to both reflect and create conceptions of personal identity. Several correlations between name meanings and practices and various sociocultural variables are presented.

This article retests several hypotheses from Swanson’s (1960) study on the origins of religious belief. The author finds support for an association between high gods and large communities, multiple levels of political hierarchy, and social differentiation. No support is found for Swanson’s other hypotheses concerning polytheism, ancestral spirits, reincarnation, the soul, witchcraft, and morality and their relations to social, political, and economic variables.
